Approach
Building enclosures are complex systems influenced by climate, materials, detailing, construction sequencing, and building operation. We approach every project using a careful, methodical process grounded in engineering and building science:
1. Independent, Objective Evaluation
All recommendations are rooted in engineering judgment, testing
Building enclosures are complex systems influenced by climate, materials, detailing, construction sequencing, and building operation. We approach every project using a careful, methodical process grounded in engineering and building science:
1. Independent, Objective Evaluation
All recommendations are rooted in engineering judgment, testing, research, and performance data — never product sales or manufacturer influence.
2. Practical, Constructible Solutions
Recommendations must work in the field. Our deliverables focus on clear details, realistic solutions, and guidance that construction teams can implement successfully.
3. Early Risk Prevention & Effective Troubleshooting
We help project teams identify potential envelope failures early in design or construction. When issues arise after completion, we apply systematic diagnostics to find root causes and recommend durable solutions.
